Mechanism and Optimization Strategies of Color Difference in Bus Painting
The bus painting is required to meet the demands of appearance quality,among which appearance color difference is a major challenge.The improper control or inaccurate judgment of color difference will bring huge economic losses to the painting industry.This article first introduces the theoretical model of color difference,and then proposes the information source,propagation medium and receiver mechanism of color difference generation from the viewpoint of color-perception process essential factor.Based on the mechanism of color difference,the influencing factors of color difference based on the bus painting condition are further analyzed,including paint composition,film thickness,observation angle and film color,etc.Finally,based on the three mechanisms and related generation factors,the strategies for color differences are proposed,aiming to achieve better color difference control and more accurate color difference judgment from the perspective,in regard of process conditions and judgment methods.
